Used a self made virgina out of a aluminium tube with a cut off motorcycle inner tube pushed through the tube and streched over each end filled with hair conditioner for lube to make a tight pussy then trap one end in a drawer and stand up and masturbate thrusting my cock in and out like having normal sex, did this when I was in my teens in the 60s before discovering real sex, I might try it again for old times sake, used to achieve incredible ejaculations,
Well, I have a left-handed monkey wrench! But seriously, mostly a slim dildo if a real cock is not available.
I've tri3ed just about everything you can Imagine--and still willing to try anything you might suggest.
